What auxiliary SSDI benefits are and how much they pay

Auxiliary benefits are payments to family members of someone receiving SSDI — typically a spouse, ex-spouse, or child. The amount each family member receives is a percentage of the worker's own benefit amount, not a separate calculation. Most commonly, a spouse or ex-spouse gets 32.5% to 50% of the worker's benefit, and each child gets 75% of the worker's benefit, though the total paid to the whole family has a cap.

The exact percentage depends on the family member's relationship to the worker and their age. A spouse at full retirement age receives 50% of the worker's benefit. A spouse under full retirement age receives less — the reduction varies by how many months before their own full retirement age they claim. Children under 18 (or 19 if still in high school) receive 75% each. Adult children with disabilities that began before age 22 can receive 75% for life.

Because of the family maximum, the total amount paid to all family members combined cannot exceed 150% to 180% of the worker's own benefit. If the family is large, each person's payment shrinks proportionally. For example, if the worker's benefit is $2,000 per month and the family maximum is $3,000, and there are four family members receiving benefits, each person's share gets reduced so the total stays at or below $3,000.

Key Takeaways

  • A spouse at full retirement age receives 50% of the worker's benefit amount; a spouse under full retirement age receives a smaller percentage that depends on their age.
  • Each child under 18 (or 19 if in high school) receives 75% of the worker's benefit.
  • Adult children disabled before age 22 can receive 75% of the worker's benefit for life.
  • The family maximum limits total payments to the entire family to between 150% and 180% of the worker's benefit, so larger families see reduced individual payments.
  • Auxiliary benefits are paid only if the worker is receiving SSDI; they do not exist separately from the worker's own claim.

How the percentage changes based on age and relationship

The relationship to the worker and the family member's age determine the percentage. A spouse at full retirement age — which is 66 to 67 depending on birth year — receives exactly 50% of the worker's benefit. A spouse who claims before reaching full retirement age receives a reduced percentage. The reduction is roughly 0.35% for each month before full retirement age, so a spouse claiming at 62 (the earliest age) might receive around 32.5% to 35% depending on their birth year.

Children have a simpler rule: each child under 18 receives 75% of the worker's benefit. If the child is still in high school, the benefit continues until age 19. Once a child turns 19 and is no longer in high school, the benefit stops, even if the worker is still receiving SSDI.

Adult children who became disabled before turning 22 are treated differently. They can receive 75% of the worker's benefit for as long as they remain disabled, regardless of age. The disability must have started before age 22 and must meet Social Security's definition of disability — the same standard used for SSDI itself.

Understanding the family maximum and how it reduces individual payments

The family maximum is a cap on the total amount Social Security pays to all family members combined. It is set between 150% and 180% of the worker's primary insurance amount — the exact percentage depends on the worker's birth year and when they claim. For a worker whose own benefit is $2,000 per month, the family maximum might be $3,000 to $3,600 per month total.

When the sum of all family members' individual percentages exceeds the family maximum, Social Security reduces each person's payment proportionally. For example, if the worker receives $2,000, a spouse would normally receive $1,000 (50%), and two children would each normally receive $1,500 (75% each), the total would be $5,000. But if the family maximum is $3,000, Social Security divides $3,000 among the three family members, so each receives $1,000 instead of their full percentage amount.

The family maximum applies only to auxiliary benefits, not to the worker's own payment. The worker always receives their full benefit amount. Only the family members' shares are reduced if the total would exceed the cap.

How auxiliary benefits change if the worker dies

If the SSDI worker dies, auxiliary benefits do not automatically end. Instead, the family members may become may be able to access for survivor benefits under Social Security's survivor insurance program. The percentages and family maximum work similarly, but the amounts are based on the worker's earnings record at the time of death, not on their SSDI benefit amount.

A widow or widower at full retirement age receives 100% of the worker's primary insurance amount. A widow or widower under full retirement age receives a reduced percentage. Children under 18 (or 19 if in high school) receive 75% each. The family maximum for survivor benefits is also between 150% and 180% of the worker's primary insurance amount.

The key difference is that survivor benefits are a separate program with its own rules, even though the percentages look similar. If you are receiving auxiliary SSDI benefits and the worker passes away, contact Social Security to report the death and learn whether you are may be able to access for survivor benefits instead.

What happens to auxiliary benefits when the worker reaches full retirement age

Auxiliary benefits do not end when the worker reaches full retirement age. The worker continues to receive their SSDI benefit, and family members continue to receive their auxiliary benefits at the same percentage. Reaching full retirement age does not change the amount paid to auxiliary beneficiaries.

However, if the worker chooses to suspend their SSDI benefit after reaching full retirement age — a rare choice — auxiliary benefits would also be suspended. This almost never happens because SSDI is not designed to be suspended the way retirement benefits can be. For practical purposes, once auxiliary benefits begin, they continue as long as the worker is receiving SSDI and the family member remains in an may be able to access category.

Auxiliary benefits for ex-spouses and divorced family members

An ex-spouse can receive auxiliary benefits on the worker's SSDI record if the marriage lasted at least 10 years and the ex-spouse is at least 62 years old (or any age if caring for the worker's child under 16). The ex-spouse receives the same percentage as a current spouse of the same age — 50% at full retirement age, or a reduced percentage if younger.

The ex-spouse does not need the worker's permission to claim, and claiming does not reduce the amount the worker receives or the amount a current spouse receives. However, the family maximum still applies to all family members combined, including ex-spouses. If there are multiple ex-spouses and a current spouse, all their benefits count toward the same family maximum.

Children of the worker receive auxiliary benefits regardless of whether the parents are married, divorced, or never married. The percentage and family maximum rules are the same.

How work and other income affect auxiliary benefit amounts

Auxiliary benefits are not reduced if the family member works or has other income. Unlike some other benefit programs, SSDI does not have an earnings test for auxiliary beneficiaries. A spouse, child, or ex-spouse can earn any amount and still receive their full auxiliary benefit.

However, if the auxiliary beneficiary is also receiving their own Social Security retirement or disability benefit, Social Security will pay only the higher of the two amounts, not both. This is called the deemed filing rule. For example, if a spouse is may be able to access for their own retirement benefit of $800 per month and an auxiliary benefit of $1,000 per month, they receive $1,000 — not $1,800.

Frequently Asked Questions

Can I receive auxiliary benefits if the worker is not yet 65?

Yes. Auxiliary benefits are based on the worker receiving SSDI, not on their age. A worker can receive SSDI at any age if they meet the disability standard. Family members become may be able to access for auxiliary benefits as soon as the worker's SSDI claim is approved, regardless of the worker's age.

What if I'm a stepchild or grandchild — can I receive auxiliary benefits?

Stepchildren can receive auxiliary benefits if they were legally adopted by the worker or if the marriage creating the stepchild relationship occurred before the child turned 18. Grandchildren and other relatives generally cannot receive auxiliary benefits unless they meet specific conditions, such as being legally adopted or having the worker as their legal guardian before age 18.

Does the family maximum change if a family member stops receiving benefits?

Yes. The family maximum is applied to whoever is currently receiving benefits. If one child turns 19 and stops receiving benefits, the remaining family members' payments may increase because the total family payment is now spread among fewer people. Social Security recalculates the reduction automatically.

What if the worker remarries — do auxiliary benefits change?

If the worker remarries, the new spouse can become an auxiliary beneficiary if they meet the age and relationship requirements. The family maximum still applies to all family members combined, so the total payment is divided among more people. The worker's own benefit does not change.

How do I report a change in family status that might affect auxiliary benefits?

Contact Social Security directly at 1-800-772-1213 or visit your local Social Security office. Report changes such as a family member turning 19, a child leaving high school, a marriage, a divorce, or a death. Social Security will update the record and adjust payments if needed.
